	Right, I want to disable one or more hostgroups while preserving the 
inherited list.

	I have requested '-' as an enhancement.

	I'm not sure how I could use "hostgroups actuallocation, 
!mainlocation", though. My thought was that I'd have a hostgroup 
'unlocated' with membership consisting of all hosts not in any of our 
location hostgroups. This would make it straightforward to find hosts 
without a specified location and add an appropriate location hostgroup 
to each.

Thanks,
